  # Turn - Pretty Unit Test Runner for Ruby
  #  
  # SYNOPSIS
  #   turn [OPTIONS] [RUN MODE] [OUTPUT MODE] [TEST GLOBS ...]
  #  
  # GENERAL OPTIONS
  #     -I, --loadpath=PATHS             add paths to $LOAD_PATH
  #     -r, --require=LIBS               require libraries
  #     -n, --name=PATTERN               only run tests that match PATTERN
  #     -c, --case=PATTERN               only run test cases that match PATTERN
  #     -b, --backtrace, --trace INT     Limit the number of lines of backtrace.
  #         --natural                    Show natualized test names.
  #         --[no-]ansi                  Force use of ANSI codes on or off.
  #         --log                        log results to a file
  #         --live                       do not use local load path
  #  
  # RUN MODES
  #         --normal                     run all tests in a single process [default]
  #         --solo                       run each test in a separate process
  #         --cross                      run each pair of test files in a separate process
  #  
  # OUTPUT MODES
  #     -O, --outline                    turn's original case/test outline mode
  #     -P, --progress                   indicates progress with progress bar
  #     -D, --dot, --dotted              test-unit's traditonal dot-progress mode
  #     -R, -T, --pretty                 new pretty output mode [default]
  #     -C, --cue                        cue for action on each failure/error
  #     -M, --marshal                    dump output as YAML (normal run mode only)
  #  
  # COMMAND OPTIONS
  #         --debug                      turn debug mode on
  #         --version                    display version
  #     -h, --help                       display this help information
